VENDING-MACHINE.

Specification of Letters Patent.

Original application filed-August 13, 1915, Serial No. 45,299. Divided and this application filed July 24,

1916. Serial No. 110,914.

T 0 all whom it may concern:

Be it known that I, SAMUEL M. COFFMAN, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, haveinvented certain new and useful Improvements in Vending-Machines, of which the following is a specification.

My invention relates to improvements in vending machines, and the present application is a division of the parent application filed August 13,1915, Serial No. 45,299. The present application relates more particularly to the web feeding mechanism and means to prevent the web or webs from adhering to said feeding mechanism, especially when the webs consist of postage stamps with the usual adhesive coating on: one side thereof.

Referring to the accompanying drawings which illustrate the invention:

Figure 1 is a vertical section of the machine with some of the parts removed.

Fig. 2 is an enlarged vertical section of a portion of the interior mechanism removed from the case.

Fig. 3 is a section on line III-J11 of Fig. 4, with some of the parts removed.

Fig. 4 is a plan view of most of the mechanism disclosed by Figs. 1 and 2.

Fig. 5 is an inverted plan view of webholding means.

Fig. 6 is a longitudinal section of the webholding means and a web guide.

Fig. 7 is a section of the web-holding means and the Web guide.

Fig. 8 is a slde elevation partly in section of the major portion of the interior mechanism. I

Fig. 9 is a rear elevation of part of the mechanism for simultaneously releasing .all of the webs, so that they may be fed forwardly preparatory to having stamps severed therefrom. Y r

Fig. 10 is a rear elevation of a, part of the mechanism for releasing but one of the webs preparatory to advancing the same.

Fig. ll'is an elevation artly in section of a pawl and a ratchet w eel, and adjacent mechanism.

Referring now in detail to the various parts, 1 designates a case provided with a coin chute 2 and a delivery chute 3, through which latter the articles to be vended are discharged.

4 designates a table resting upon the bottom of the case and provided with two vertical plates 5, spaced apart as disclosed by Fig. 4. The upper ends of the plates 5 are united by a transverse bar G'carrying a pair of superimposed plates 7, united by transverse bars 8 and 9.

1O designates a pin extending through the plates 7 and constituting a fulcrum for a plurality of rock frames 11 mounting at their forward ends feed rolls 12 which cooperate with an. underlying feed roll or rolls 18 in advancing certain ticket, stamp, or other webs 14 into position over a stationary blade 15, fixed to the front sides of the plates 5. Said stationary blade 15 coacts with a rotary blade 16 in severing the webs 14 into proper lengths.

The blade 16 is fixed upon a sh aft 17 journaled in bearings 18 and extending through the front side of the case 1, where it is provided with a crank 18, or other suitable means, whereby it maybe rotated to actuate the feed rolls and cause them to advance the Webs 14. The shaft 17 is provided with a fixedly-mounted bevel gear 19, which drives a bevel gear 20 fixed to one end of the shaft carrying the feed rolls 13, which in turn .rotate the upper feed rolls 12, held in frictional engagement with the upper surface of the webs 14 through the intermediacy of springs 21, interposed between the upper forward portions of the rock-frames 11 and set screws 22, which latter are threaded through the transverse bar 9 to regulate the tension of said springs 21.

When any of the feed rolls 12 are raised out of contact with their respective webs 14, the adhesive coating on the latter will not adhere to the feed rolls 13,- as would likely be the case were said webs 14 subjected to the pressure of the feed rolls 12. The feed rolls 12 are raised after the webs 14 have been severed by the blades 15 and 16 through the intermediacy of a stud or cam 23 and a lever 24, which latter is provided at one end .with a laterally-extending arm 25 for engagement with said cam 23. As disclosed by Fig. 1, the cam 23 is fixed to the shaft 17, while the lever 24, which is U-shaped, is fulcrumed upon the pivot 10 and extends across the upper rear portions of the rock-frames 11 to depress said rear portions and raise the feed rolls 12, when the cam 23 passes beneath the 25.

The Webs 14 are wound upon spools 26 and threaded through tubular guides 27, secured upon the bar 6 by set screws 27 threaded through the bar 8. When the Webs 14 consist of postage stamps or other like perforated strips, resilient fingers 28 are provided with downturned forward terminals to pass through perforations 29, in the guides 27, and the perforations in the webs 14 to prevent forward or backward movement thereof when the feed rolls 12 are in raised position.

The fingers 28 are arranged in housings 30, fixed to the upper sides of the guides 27 and provided with levers '31, 31 and 31 having forward transverse portions 32, underlying said fingers 28 to raise the same from the perforations. The levers 31, 31 and 31 are actuated by presser feet 33, 33* and 33*, Fig. 4, depending from a rockframe 34, controlled by the web-selecting means. A spring 35 secured to the bar 9, normally holds the rock-frame 34 in raised position.

The drive shaft 17 is held from backward rotation by a pawl 40 and a ratchet wheel 42, which latter is fixedly-mounted upon the rear end of said shaft 17, while the pawl 40 is pivotally mounted at the rear end of the frame 5.

The ratchet wheel 42 is provided with a wrist pin 43, which projects into the grooved portion of a lever 45, Figs. 8 and 11, fulcrumed at 46 and pivotally connected at its free end to a depending llnk 47, pivoted at its lower end to a bell-crank 48, fulcrumed at 50 and pivotally connected at its lowerend to a plunger 51, extending forwardly through slots 52 and 53, in the coin chute 2, Fig. 8. The plunger 51 is normally held against the bottom of the slot 52, by a coiled spring 55 connected to the rear end of said plunger and a pin 56, carried by the bell-crank48.

The plunger 51 constitutes an important feature of the stamp selecting mechanism, which embodies bell-cranks 60, 61 and 62, Fig. 8, the rock frame 34, feed rolls 12 and 13, and the fingers 28. The rock frame 34 is connected to the bell-cranks and 62, through the intermediacy of connecting rods 64 and 65, having pin-and-slot connections 67 and 68, respectively, with the adjacent side of the rock frame 34, Figs. 8 and 9.

The bell-cranks 60, 61 and 62 .are fulcrumed upon a common pivot 71 and provided at their lower ends with superimbeneath the arm 25 of the lever 24, where-' upon the feed rolls 12 are immediately forced downwardly into contact with the webs 14 through the intermediacy of the springs 21 and the rock-frames 11. The webs being thus grasped by the feed rolls 12 and 13, are fed forwardly until a row of perforations register with the blade 15-, whereupon they are severed by the blades 15 and 16, and the severed portions drop through the discharge chute 3. Just before the webs are severed the cam 23 passes beneath the lateral arm 25 of the lever 24,

thereby causing the latter to rock the frames 11, which in turn lift the feed rolls 12 and hold them in raised position until the shaft 17 is again rotated and carries the cam 23 out of engagement with the lateral arm 25. As the shaft 17 rotates the ratchet wheel 42 causes the plunger 51 to advance through intermediacy of the intervening mechanism and be guided by the coin inserted in the chute 2, into engagement with one of the later extensions on the bellcranks. If the coin be of small diameter such as a dime, the plunger 51 will be uided into engagementwith the extension (5 and actuate the bell-crank 62, which will operate the rock frame 34, causing the presser feet 33, 33 a.nd.33 to actuate the levers 31, 31 and 31, which raise the respective fingers 28 out of the perforations of the webs, so that the same may be advanced by the feed rolls 12 and 13.

1f the coin should be of large diameter such as a nickel, the foregoing operation will be repeated, excepting that the rock frame 34 will be actuated through the bell-crank 60, into the lateral extension 73 of which the plunger 51 will be guided by the periphery of such nickel.

If the coin be of intermediate diameter such as a penny, it will guide the plunger against the extension 74 of the bell-crank 61 and cause the same to pull the rod 80 downwardly and cause the lever 31 to raise the fingers 28 controlled thereby out of the perforations of but one web.

Asthe complete selecting mechanism whereby a greater number of stamps are dispensed for a dime than a nickel, has been fully set forth in the parent case it is .not

considered necessary to go into further dcscription thereof.

' The means for stopping the rotary blade 16 after severing the webs, has been pointed out in the parent case and hence it is deemed unnecessary to refer further thereto at this time.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:
